Add each video's duration using our calculator. Enter hours, minutes, and seconds for each video, then click "Calculate Total." The tool adds all durations and shows the total in multiple formats (HH:MM:SS, hours, minutes, seconds).

At 1.5x speed, you save 33% of the original time. A 60-minute video takes 40 minutes. At 2x speed, you save 50%—a 60-minute video takes 30 minutes. Use our Speed Calculator tab for exact calculations.

Divide by 60. The whole number is hours, the remainder is minutes. Example: 157 minutes ÷ 60 = 2 hours 37 minutes (2 × 60 = 120, remainder = 37). Use our Convert tab for instant conversions.

Research suggests 6-12 minutes is optimal for learning videos. Attention drops significantly after 15 minutes. Break longer content into chapters and take breaks every 25-30 minutes (Pomodoro technique).

Impossible! Over 500 hours of video are uploaded every minute. Even watching 24/7 at 2x speed, you'd fall further behind. As of 2024, there are billions of hours of content on YouTube.

Most platforms count watch time when you've viewed a significant portion (usually 30+ seconds or a percentage of the video). Skipping, pausing, and rewinding may affect how time is calculated for analytics.

Yes! Use the formula: New Time = Original Time ÷ Speed. For example, a 2-hour video at 1.25x speed: 120 minutes ÷ 1.25 = 96 minutes (1 hour 36 minutes).

A typical Netflix season has 8-10 episodes at 45-60 minutes each, totaling 6-10 hours. Shorter series like limited series may be 6 episodes (4-6 hours total). Use our calculator to add episode lengths.

Experts recommend limiting recreational screen time to 2-3 hours daily for adults. For children, 1-2 hours is recommended. Take breaks every 20-30 minutes to reduce eye strain (20-20-20 rule).

Yes! Time calculation works the same for any media—podcasts, audiobooks, music playlists, or video. Enter durations and calculate totals exactly the same way.
